Plug valves with single or double flush acc.to ANSI is applicable to the cutting and connection of pipelines medium in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc, under nominal pressure of CLASS 150~300LBS,and working temperature of -29~ 180°C.
1/ The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2/ Its sealing is realized by the sealing face of the sleeve. It has particular 360 degrees metal edge for protection and fixing of the sleeve.
3/ There is no cavity in the valve for accumulation of medium.
4/ Metal edge provides the function of self- cleaning when the plug is rotated, applicable to the operation condition that is glutinous and easy to scale.
5/ Its characteristic double-direction flow makes installation and use more convenient.
6/ The materials of the parts and sizes of flanges can be reasonably configured according to the actual operation condition of the requirements of the customers, so as to meet the various needs of engineering.
